It Willbe seen that the roller bearing box 6 fits against the inside surface 7of the remaining portion of the journal box 3. The top lug 8 of theroller bearing box 6 has a transversely crowned top surface 9 whichreceives the vertical side frame load through the surface 7 of theinside top Wall of the A. R. A.r box.

The roller bearing box 6 is inserted from the iront of the side frame 2and is held in position byv a retainer block 10, Which is bolt- I Y edinto a recess 11 in the top lug 8. The retainer has an outwardvprojection 12 with a radial bearing surface 13, Which takes up sidethrust against the frame 2. A correkNo. zzazaarnenewea xpm 15, 1.931.

It will therefore be seen that my invention makes it ossible to apply tothe standard t pe of si e frame and integral box construetiona rollerbearin type of journal box without interfering wit the ease ofremovability of the cover and thrust member of such a box as is shown inmy co-pending application, Serial No. 248,343, filed January 21, 1928.

The terms and expressions which I have employed are used as terms ofdescription and not of limitation, and I have no intention, in the useof such terms and expressions, of

- excluding any mechanical equivalents of the portion o `features shownand described, or portions thereof, but recognize that variousstructural modifications are possible within the scope of the inventionclaimed.

What I claim is:

1. The method of adapting a plain bearing,integral box side frame foruse with roller bearings comprisinn` removing the end portion of saidintegral tbox and inserting, within the remaining portion of said box, ahousin containing roller bearings.

2. 'T e method of adapting a plain bearing, integral box side frame foruse with roller bearings comprising removing the end said integral boxand inserting, within the remaining portion of said box, a housingcontaining roller bearings, and securing to one of said parts means forretaining said housing in position.

3. The method of adapting a plain bearing, integral box side frame foruse with ro ler bearings comprising removing the end `'portion of saidintegral box and inserting,

within the remaining portion of said box, a housing containing rollerbearings, and limiting relative movement between said housing and boxportions in all directions.

4. The method of adapting for use with roller bearings a plain bearingintegral box side frame includin central wedge block abutments, said metod comprisin remov ing an end portion of said integral ox, cutting awayparts of said abutments, and inserting into the remaining portion ofsaid box a housing containing roller bearings.

5. In combination, a side frame including a-portion of a lain bearingjournal-box integral with said side frame, a roller bearin 'journal-boxhaving a bearing within sai portion, and means on said roller bearingjournal box for maintaining it in operative relation with said portion.

L 6. In'combination, a side frame including a portion of aplain bearingjournal-box intealiwith sai side frame, a roller bearing journalboxhaving a bearing within said portion, means on said roller bearingjournal Ibox for maintaining it in operative relation with said portionand means for transmitting the thrust from the roller bearing journa boxto said portion and thence to the side frame.

7. In combination, a side frame including a portion of a plain bearingjournal-box integral with said side frame, a roller bearin journal boxhaving on its top an arc sh exterior surface bearing against theinterior surface of said portion to permit a limited rocking movementbetween said box and said portion, and means on said box for maintainingit in operative relation with said portion.

8. In combination, a side frame including a portion of a plain bearingjournal-box integral with said side frame, a roller bearin journal boxhaving a plurality of arc shap exterior surfaces bearing against theinterior surfaces of said portion to permit a limited rocking movementbetween said box and saidL portion, and means on said box formaintaining it in operative relation with said portion.

9. In combination, a side frame including a portion of a plain bearingjournal-box integral with said side frame a rolleri bear-A ing Journalbox havin a bearlng within said portion, and stops on t e box eng 'ngshoulders on said portion adapted to maintain said box and said portionin operative relation.

10. In combination, a side frame including a portion of a lain bearingjournal-box integral with said t side frame, a roller bear Journal boxhaving a bearing within portion, and a stop removably secured top saidbox after seating in the bearing in said portion to maintain said boxand said portion in operative relation.

11. In combination, a side frame including a portion of a plain bearingjournal-box in-A tegral with said side frame, and a roller bearingjournal-box having a bearing within said portion.

In testimony whereof, I have signed my name to this specification this20th day of.rn0
